Here's what I think...
The people who point this out (Not you guys, the people who are actually trying to ruin Disney) are either:
a) People who have NO lives, and just sit around trying to ruin other peoples honest fun, watching movies frame by endless frame to try and catch out anything that might look like the word "sex"
Here's a great example.

In all honesty I think it says SFX, people put in little notes/signs/in-jokes in movies ALL THE TIME! If you can find a movie that doesn't have one single in-joke...I will eat my digital hat :\
In-jokes are as little as putting a Shaun of the Dead DVD in the movie Hot Fuzz

Or they can be as big as the SFX in TLK or the Wilhelm Scream in nearly every movie since 1951
(another note: if you don't know any of the movies or anything I'm on about - google is your friend)
However, Person b) wouldn't just pick on huge Movie making companies like Disney, they'd probably complain because a banana and two plums are arranged in a suspicious manner in a fruit bowl.
Grar, this subject just angers me >.<
EDIT: I've attached a picture that proves people actaully LOOK for bad words, instead of them purposefully being there.
I went through a few of my pictures...and what ho! I found the word sex or an innuendo in all of them!
Beward of the picture, it's got naughty words on it
